BIOFOS Utility, treating wastewater in the Greater Copenhagen area, has enhanced the operation of its three large treatment plants through a commitment to sustainability and innovation. The goal has been to maximise the utilisation of existing facilities, minimise environmental impact and ensure optimal and compliant operation under diverse conditions, including varying  weather patterns. The primary challenge has been to improve operational efficiency, particularly in response to the growing population in the catchment area.

To meet these challenges, BIOFOS initiated a collaboration with Krüger A/S 20 years ago to develop and implement data-driven technology, today known as Hubgrade. Over the years, numerous projects have been undertaken, ranging from enhancing process understanding to developing new software. This approach has revolutionised plant operations, leveraging specific process data and external inputs such as rainfall, electricity prices and effluent regulations.

Operators now possess the tools and knowledge to manage the complexities of treatment effectively, setting targets in real-time that balance priorities such as cost efficiency, capacity utilisation, compliance and climate impact.
